MocoTyper is a free software (there will always be a free version, alongside a premium version in the future). Acquiring a Code Signing Certificate to remove these warnings requires a significant annual cost. However, you can be completely assured of the software's security as the application has been strictly vetted and guaranteed to be free of malware.
How to install:
- Windows: When the 'Windows protected your PC' screen appears, click 'More info' -> 'Run anyway'.
- macOS: Right-click the application and select 'Open', or go to System Settings -> Privacy & Security to allow the app to open.
